The quantity q varies inversely with the square of m and directly with the product of r and x. When q is 2.5, mis 4 and the
saveliy_v [14]

Answer:

The constant of proportionality is 5.

Step-by-step explanation:

If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is

q=k\frac{rx}{m^2}

When q=2.5, m= 4 and the

product of rx = 8.

We plug in this values to get;

2.5=k(\frac{8}{4^2})

2.5=k(\frac{8}{16})

2.5=\frac{1}{2}k

Multiply both sides by 2

k=2.5\times 2=5

The constant of proportionality is 5.

Torrie could buy 8 jars of peanut butter for 27.12 or 7 jars of peanut butter for 26.53 what is the difference in the unit rates
Elan Coil [88]

Answer:

The difference in the unit rates of the jars of peanut butter is 0.4.

Step-by-step explanation:

In order to find the unit rates, you have to divide each price for the amount of units purchased with that price, which is:

27.12/8=3.39

26.53/7=3.79

Now, that you have the unit rate for each case, you have to subtract 3.39 from 3.79 to find the difference in the unit rates:

3.79-3.39=0.4

According to this, the answer is that the difference in the unit rates of the jars of peanut butter is 0.4.
